During the month, contributed to the deepflowio/deepflow repository by delivering a targeted bug fix that enhanced data accuracy and governance for organization-scoped analytics. Focused on backend development using Go and SQL, the work addressed Custom Business Service Filtering in query execution by ensuring organization-based filters were consistently applied across relevant tables, excluding alert_event. The default filter condition was updated from 1=1 to 1!=1, improving the reliability of analytics dashboards and data security. The fix, traceable through a dedicated commit in the Slimit component, demonstrated careful debugging and maintainability improvements within the project’s backend data processing pipeline.
